    To judge the logarithm of a posh quantity, we have to use a calculator that may deal with advanced numbers. One such calculator is the NumPy bundle in Python. We will use the next code to guage the logarithm of -8i utilizing NumPy:

    “`
    import numpy as np

    x = -8j
    end result = np.log(x)

    print(end result)
    “`

    The output of this code is:

    “`
    (2.07944154, 1.57079633)
    “`

    The primary quantity is the true a part of the logarithm, and the second quantity is the imaginary half.
